I In my co-pendingapplication for Letters Patent Serial Number 276,149, filed May, 8, 1928, I have'described an automatic coupling arrangement of novel" and advantageous design, and I have also shown how, with various modifications, my improved coupling ap- & paratus may be used on vehicles not fitted with" automatic coupling apparatus during 9 what I' have therein called the transition 10 centrebuffer and hoo coupling.

period to couple u with" vehicles of the The presentinvention is devised with the object {of showing means for applying my improved 'couplingapparatus to couplers of the [ordinary chain andhook "type, or the turnbuckle and hook type during suchtransition period, 7 it being understood that when such transition period is over my coupling apparatus..will be identical with that shown and described in my co pendingapplication,

' apparatus is therein givenl shall confine myandaccordingly as a .full description of such self in the present application'merely to the particularapplication of my improved automatic coupling" mechanism tothechamand hook typefor the turnbuckle and hooktype invention with particular reference to my imof coupling during the transition period.

It mustbe 7 clearly understood however that although I vhave described my present proved 'type' of coupler, the scope'of the invention is not limited thereto but is equally applicable to any usual type of: coupler of th'chain and hook orr'turnbuckle and hook type ofcoupler. or I 'As willbehereinafter more clearly shown the placing of the transitionhook during the transition period inrelation to the coupler headis so disposed that the knuckle and. the locking pin can bemounted during such period, thus providing for the automatic working .of the coupler head during such periodwhen two of my automatic coupler; & heads meet. This result is accomplished by 7 means of the transition hook being housed to one side; of the coupler head, and. on the underside thereof, thus allowing the partial rotation} of the knuckle.

vshowing inyl improved form of liookand couplerhead,"and'Figure 8'is anadapt'ation of the improved hook shown in Figurel as used during said transition period in conjunction with a known form ofturnbuckle and shackle" as commonly usedon passenger stock. Referring now to the drawings the point 12. of the hook 9 is housed within the coupler j head 1, being passed vertically upwards through a suitably shaped hole 11 in the lower flange of the couplerhead 1. The point 12 of the hook 9 is maintained in the desired position by suitable means such as a pingl3c securely fixed by any known means to the 'f accompanying drawings; 'in'which: Figure 7 11s an elevation jshowing one/way ofcoug 7 hook 9, the said pin 13' projecting laterally I on both sides ofthe'hook 9. These projecting ends are designed to support the hook 9 and permit same to vslide or have rotary'move ment. In Figure 3 the hook 9 is shown attached: for use with the centre hook coupling where the usual known type of turnbuckle 14 and shackles l5areused.

In'Figures land 2 is shown the applica- I tion of my improved coupling apparatus r coupled during the transition period with r the coupling of the centre chain and hook type wherein a special hook 9 previously de- 5 scribed, is securely housed withinthe coupler .head 1. It will be noted that the coupler head i 1 in this case isfitted with knuckle 5 and locking pin i complete with alliattachments providing for. automatic coupling when two vei hiclesmeet, each being fitted with this con 1 pler head, the hook 9 beingso placed onone I I side of coupler head 1 that the saidhook 9 and attached'chain-IO will hang vertically i clear to allow of the rotation ofthe tail 7 of 15 the knuckle 5 during automatic coupling.

' With respect to the centreturnhuckle and i shackletype shown in Figure 3 the operar tioniissimilar tothat described for Figures- V '1; and 2.
